Abstract

This article illustrates how the overhead projector can be used as a light source in some peculiar ways for physics demonstrations. Five examples are included:

  1. Study of chromatic aberration
  2. Making giant Newton’s rings
  3. Comparison of the rate of heat absorption by different surfaces
  4. Demonstration of greenhouse effect
  5. Production of an intense parallel light beam
